Mohegan Resorts Mass, an affiliate of the tribe, announced Thursday it will retain CBRE/Grossman Retail Advisors to study development options for 152 acres of land in Palmer, which Mohegan Resorts Mass controls through a long-term lease.

The land off Exit 8 of the Massachusetts Turnpike was envisioned as the site of a $1 billion casino and water park until voters in Palmer rejected the plan on Nov. 5.

"We've invested over $10 million into this property alone, and millions more into activities related to its development," Mohegan Tribal Gaming Authority CEO Mitchell Etess said in a statement. "CBRE is the nation's premier real estate advisory firm, and they will assist us in reviewing what options may exist for non-gaming development on our site in Palmer."

The advisers will perform a "highest and best use" analysis of the site, which could include potential partners. The tribe did not say when the report is expected to be complete.

After the Nov. 5 vote in Palmer, Mohegan Sun teamed with Revere, Mass., in a proposal for a casino at Suffolk Downs racetrack on Boston's North Shore. The plan faces a municipal vote Tuesday and competition from a rival proposal in Everett, Mass.
